A.11 AXI interface signals
The AXI protocol supports clock, configuration, and data handling signals when the processor uses this
protocol for the master memory interface.
This interface exists only if the processor is configured to have the AXI interface.
All AXI channels must be balanced with respect to CLKIN and timed relative to ACLKENM.
